Application February -15, 1944,,Serial'No. spasm .16 Claims. (oi. 30-296) This invention relatesto a weapon and inore particularly to a knife designed to be attached (Granted-under the act iii-March 3, 1883, as

amended April 30, .1928; 370 0. G. 151) blades in raised positionfFig 2 is an end view to the. forearm for. use in hand-to-haiid combat.

- Weapons of this type have been desi d :with fixed blades, the ends of which are rigidly attached to transverse members shaped to fit the forearm. While theseweapons lend themselves to use'whereverthe enemy may be contacted,

they are particularly advantageous in landing operations or raids where small landing craft are 10 used to carry the attacking troops from transports anchored several miles offshore to the scene of action. As there is no time for weapons of this type after landing, they are afiixed before entering the landing-boats. In a small pitching crowded boat-there is the very real darlger of the occupants injuring each other when the fixed blade type is used. Such weapons are also dangerous and difilcult to carry and store when not in use.

It is the object of'this invention to provide a thereof; Fig.3 is a viewof the other end; Fig. 4 is a section taken on the line H of Fig.1; Fig. 5 is a section taken on the line 5 5 of Fig. 1

this invention to pro- Referring to the drawings, the frame, 40 is formed of semicircular end pieces II and I2, rigidly connected by acurved steel plate l3. Other connecting means such as rods or bars may be] used, but the plate hasthe advantage of protecting the arm of the wearer. Straps II and i6 are riveted to theframe, one at either end, adjacent the end pieces II and I2, and are provided with buckles l5 and 81. .These straps serve to fasten the weapon'to the forearm of the person using the same. A 'filler 41 may be attached to one end of the frame on the side adjacent of blades in one or more posithe wrist to assist in keeping the weapon in position. The filler ilisshown as a wood block with a flat side fastened to the frame, but any other suitable material, such as-a pad, may be usedinstead. v

Blades l8, l8 and -20, mounted on and carried by the'frame 50,- are of any desired configuration and have the outer edges thereof sharpened.

These blades have pintles 2i and 22 projecting outwardly from the ends of the back of the blades *and may be formed integral therewithbrat- The embodiment of th'e'invention as disclosed,

in the drawings comprises a frame carrying several pivotally mounted blades provided, with means for rotating the same from aninoperative position flatagainst the framework through an angle of approximately 90 to arr-erected or tached thereto. vThe pintles 2| are cylindrical in form and are suitably joumaied in the end piece II for free rotation therein. Pintles 22 at the other end of the blades have a portion 25, be-

' tween the end of the pintle and the blade, halfopen position with the blades substantially. vertical to the frame. The frame is semicylindrical in shape and fits around the forearm upon which it is adapted to be strapped. The actuating and locking means for the blades prevents them from being accidentally pivoted-both'when open for use and'when in closed position. When affixed to the forearm with the blades on the outer side of the arm, the weapon may be safely carried at all times and the blades instantaneously raised for use in hand-to-handcombat with the enemy.

Fig. 1 is a plan view of the weapon withthe.

-round in cross section, .asshown in Fig. 10. The

end 26 of the pintle is circular in cross section. The pintles 22 are iournaled in the end piece l2 which is L-shaped in cross section, the vertical' portion forming a rim 2'I at theouter side thereof. 'I'heface of the horizontal leg 2:! has semicylindrical recesses 24 formed therein which Journal the half-round portions 25of the-pintles 22.
